3. Lena Dunham’s “Your First Time”

In an election campaign where it felt as if every political ad was nastier than the last, actress/comedienne Lena Dunham’s “Your First Time” stood out. Loved by the left and dubbed tasteless by the right, Dunham’s ad equating first-time voting with losing one’s virginity created enormous buzz. It may not have had any effect on getting young people to the polls, but its humor and controversial tenor are likely to make it the most memorable ad of the 2012 campaign.
